My last post showed the close up view. Here you can see the block it is mounted in. It could be smaller but I'm using #12 wire and don't see the need to crowd things in the prototype.
I'm am feeding a signal into the transformer lower left and driving the telephone receiver center. It is not ear piercing but load enough I can hear it.
With all the leads attached it is not pretty but you can get a better view.
The scope tells the story. signal is passing through. Now the question is where to get the germanium? I have a couple of those 1N34As but , do I want to destroy one? Time to rumble through the junk bins.
